But why offer an API that is an attractive nuisance? I don't think that it is a burden to the user to have to specify "from 0 to 2 inches in 8 steps" instead of "from 0 to 2 inches in 1/4 inch steps". (And what if they tried to say "from 0 to 3 1/4 inches in 1/2 inch steps" ?)

And how many steps in "from 37 3/4 inches to 90 1/4 inches" ? I don't want to have to calculate that. That's what computers are for.

Your last example is no different than today's range(2, 10, 3) -- we don't get 10 or 9.
